The main difference between SPECT and PET scans is the type of radiotracers used. While SPECT scans measure gamma rays, the decay of the radiotracers used with PET scans produce small particles called positrons. A positron is a particle with roughly the same mass as an electron but oppositely charged.
What is a spect ct scan used for?
Likewise, people ask, what is a Spect CT scan used for?A single-photon emission computerized tomography (SPECT) scan lets your doctor analyze the function of some of your internal organs. A SPECT scan is a type of nuclear imaging test, which means it uses a radioactive substance and a special camera to create 3-D pictures.
what is a CT spect bone scan? Bone Scan
. A bone scan
involves injecting a small amount of a radioactive substance that attaches to the bones
. For the SPECT
(or single photon emission computed tomography
) component, the nuclear medicine gamma camera rotates 360 degrees around the body and creates pictures based on the data it obtains.
is a Spect scan the same as a CT scan?
A SPECT–CT scan is a type of nuclear medicine scan where the images or pictures from two different types of scans are combined together. The combined scan can provide precise information about how different parts of the body are working and more clearly identify problems.
How long does a Spect scan take?
The scan takes about 30 minutes and you will be asked to lie flat on our imaging table and hold very still the entire length of the exam.
What can a Spect scan diagnose?
A single photon emission computed tomography (SPECT) scan is an imaging test that shows how blood flows to tissues and organs. It may be used to help diagnose seizures, stroke, stress fractures, infections, and tumors in the spine.
Where can I get a Spect scan?
A single photon-emission computed tomography (SPECT) scan is done in a hospital nuclear medicine department or at a special radiology center by a radiologist or nuclear medicine specialist and a technologist. You will lie on a table that is hooked to a large scanner, cameras, and a computer.
What does spect stand for in medical terms?
Single Photon Emission Computed Tomography
Can a Spect scan show depression?
Brain SPECT Imaging Predicts Outcomes in Depressed Patients. New research from Amen Clinics shows that brain SPECT (single photon emission computed tomography) imaging, a study that measures blood flow and activity patterns, identifies who is more likely to get better from depression.
Can you see nerve damage in a CT scan?
Can Damaged Nerves Be Seen On An X-Ray? Damaged nerves cannot be seen on a regular X-ray. They can be seen on CAT scan or MRI, and in fact, MRI is recommended for examining details of the spinal cord.
What is spect in radiology?
Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D information.
Is a bone scan a CT scan?
A bone scan is a nuclear medicine test. If the scan shows bone damage, more tests may be needed. These tests may include 2 other types of scans. One is a computed tomography (CT) scan, and the other is a positron-emission tomography and computed tomography (PET-CT) scans.
What does a bone scan tell you?
A bone scan is an imaging test used to help diagnose problems with your bones. A bone scan is a good way to view and document abnormal metabolic activity in the bones. A bone scan can also be used to determine whether cancer has spread to the bones from another area of the body, such as the prostate or breast.
Can you eat before a Spect scan?
Nuclear Medicine Preparation. If your doctor gave you an order, please bring it with you. Do not eat or drink anything four hours before the exam.
Does a bone scan show arthritis?
Many changes that show up on a bone scan are not cancer. With arthritis, the radioactive material tends to show up on the bone surfaces of joints, not inside the bone. Typically there is no need to have yearly follow-up bone scans if you aren’t experiencing any unusual symptoms, such as persistent pain.
